Assign a Mesh/Armor Addon to another Item slot

[shazor]

Hey Guys,

i have a problem with the CK. I have 2 armor i basically want to merge into one so i decided to put the one armor in another item slot so i can wear it together with the other armor. I changed the item slot of the armor the armor addon and the nif files to 60 but the armor keeps invisible in the game. I also tried other item slots like 58, 50 but nothing seems to work. The armor used the body slot before i changed it but i guess that doesnt matter.

I attached some images of the one nif files and the 2 entries in the CK.
